Sub Cutting Out At Volume

Hey guys,

Just had a quick question - I've got a little issue with my sub in my car at the moment - when I go to turn the volume past about 15 on my HU the sub works on and off but cuts out. I've got it attached to an 800W Pioneer Monoblock Amp and the Sub is a Clarion Pro dual voice coil.

I'm not sure what I can check out on it to be honest, the power cabling for the amp is very good and I never had this problem with my old sony sub (untill I blew it up though....)

any ideas ? if I can't figure it out I may take it over to Chris at audio express to have a look for me.

Hello there,

It sounds more like ur drawing too much current out of the power side of ur amp. Is your voice coils parralelled or series, and what ohmms is it then. If it dual 2 ohmm voice coils in a parralell connection (positive to positive) (negative to negative) u will have a one ohmm load and ur amp will get hot and cut out at half volume. Most mono block amps can run 2 ohmms minimum.

Good Luck

only suggestion check all wiring is secure, maybe one of the wires inside the box is loose, or check your ground to monoblock is same size minimum as your power, not having a big enough ground will cause it to cut out, also check your rca cable, play with the ends of them and see if they cut out when you wriggle them, if its none of them may be... the devil is in your car

      Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
